Hi everyone,<br>I'm working on my images and I need your help again.<br><br>As I said this morning, I have to do:<br><br>Dfinal = Daverage < (D - 0.5)<br><br>where Dfinal, Daverage and D are 3D images. <br><br>As Sergio suggested me, I obtained<br> B = (D - 0,5)<br> with itkSubtractConstantFromImageFilter and it works great... Thanks! (I use this method and not AddConstantToImage because I have to subtract).<br><br>Then I'm trying to compare my two images Daverage and B using itkDifferenceImageFilter but I'm not able to use the result.<br><br>I think that the DifferenceImageFilter output should be an image whit pixel > and < of zero... it is ok?<br>Now I probably should save in Dfinal only the pixel < of zero; how can I read the value of each pixel and save the only ones that I wish?<br>Is there some different way to obtain Dfinal?<br><br>Sorry me for my banal question but I'm a starter in this field.<br><br>Thanks anyone who'll help me<br><br>Regards<br>Daniela<br><br> </body>
